Afternoon everyone, I'm looking at building an electric heated kettle from a keg and was wondering if anyone could recommend some heating elements, I was thinking of using washing machine ones but read that they might not do the job. Also if anyone has a parts list for making one, tools, parts etc that would be amazing, cheers

Hi Thommo, I'm the wrong person to advise you on this topic sorry, but welcome to the forum.

I'm sure if you contact them, they'll advise you accordingly.

Also, our resident technical expert, Pinto, will have some great input I'm sure. He'll be along soon.

Hi Thommo 😉

Im going to assume that you bought one of the topless keggles that Malt Miller sold cheap a while back - because using kegs from "alternative sources" and cutting the top off them with an angle grinder is naughty and not to be condoned 😉

There are several ways you can go with this, depending in the main on the volume of the keg - 50L is standard, so you'll be needing at least 3kW of heating power to bring it to the boil in a reasonable time scale; You can easily get hold of 3kW immersion heater elements, but these are (a) not that cheap and (b) require a ~60mm hole to be cut into the side of the keg, which is convex and therefore difficult to seal to a flat based element.

My recommendation is to get a 40mm HSS or TCT Holesaw and one of these :

https://www.ebay.co.uk/itm/Compatible-Burco-Water-Boiler-Element-3000W-3KW-Fits-Many-Of-Models/311748064733?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

which will require you to cut a hole in the base of the keggle, which is flatter and more convenient (less likely to boil dry)

Additionally,the last 50L I converted, I added a 2kW boosting element :

https://www.ebay.co.uk/itm/Electrical-Element-Elbow-Stainless-Steel-Heating-Tube-For-Water-Heater-220V-2KW/121807313954?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

Which means to reach boil, I can run 5kW of heating, giving a boil time of ~30 mins.  These are a lot simpler, as they just require a pair of 12mm holes to be bored in the base,

Dont forget - drilling Stainless - use slow speed (speed 1 on a cordless driver), constant firm pressure (not too hard) and a proper cutting fluid (preferably) or plenty of WD40 - once you start the hole, dont stop till you're through !

On the electrical side, you're going to need a controller so you can maintain a healthy boil, but not one so violent the boil is unmanageable - read Adrian's excellent guide to his "Boil-o-Matic" for info on that 😉

The 3kw bottom one looks good but will it not get in the way of the drain cock etc? Also would you recommend fitting a false bottom? If you have any pictures of what you made that would be great

Youtube seems a good place to see what others have done, for example...

No, the element fits with plenty of space for either a side or bottom drain to be fitted without interference.  Also, as this is a boiler, a false bottom is unnecessary, just a manifold or bazooka ( or even a straight pipe and stop worrying about a little trub going through [wink] )

I'll see if I can find any pics 😉

Nightmare to fit that element, what did you use to cover the wires underneath, back box’s aren't deep enough

100x100 adaptable box - you can get them in depths from 30-100mm.

Just cut a hole in the bottom of the box and stick them in place with silicone.

What issues did you have ? I just drilled a 40mm hole and fitted/screwed the retainer up tight
